Improvement in sawing-machines



ALFRED w. 'rowNsnEND or WASHINGTON, Disrnrc'r or COLUMBIA Letters PatentNo. 86,883, dated February 9, 1,869.

INIPROVEMENT IN SAWING-MACHINES- The Schedule referred to 1n these Letters Patent and making part cf the lame.

To all whom it ma/y concern Be it known that I, ALFRED W. TowNsHEND, of the city of Washington, and District of Columbia, have invented an Improved Machine for'Sawing Wood by Hand; and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specication, in which- Figure l represents a top view of the machine.

Figure 2, a side elevation of the same.

Figure 3 shows how the wood is secured firmly, by the rope or chain, to the notched wood-rack.

Figure 4, a front view of g. 3.

The nature of my invention consists in the construction and arrangement of the saws with weights at their front ends,l operating in guides, and a weight-plate on top of the sawsythat are moved backward and forward by a sliding frame and crank-shaft; also the adjustable wood-fastenings, with the tightening-rope and roller, operated and regulated by a crank, ratchet, and dog.

The object of my invention is to saw wood by hand, in the quickest, easiest, and cheapest manner, so as to venable every housekeeper to possess and use it to advantage.

A represents the oblong frame that supports the saws and the other devices.

B represents the crank and vmain driving toothed wheel, moving on the one end of its axle, C, and gear-V ing into a pinion-wheel, D, in front, that operates the crank-shaft E and flywheel F.

To the crank G, a pitman, H, is attached, by a pivot, and tle opposite end of pitman H is also attached, by a pivot, to the sliding cross-frame J, that slides back and forth in grooves in each side of frame A.

In front of this sliding frame J is a round cross-rod, K, to which the saws L L are attached, and operated back and forward by the frame J.

The frames M Mofthesawsare made of cast-iron,

Vwith extension-endsin front, as weights N N, to keep the saws steady, and down to their-work.

Another weight-plate, l?, is screwed fast across the tops of the saw-frames M, upon whichextra weights may be placed when required.

The ends N N of the saw-frames operate in upright guides, R, that are adjustable, wider or narrower apart, by movable screws 'or pins in the cross-piece of frame A. Llhe angular and notched wood-racks S S are also adjustable, narrower or wider apart, bythumb-screws working in a slot of the frame A. In front of the wood-racks S is a roller, T, extending across and operating in the sides of the frame A. In the centre of this roller T are a projecting pin and windlass, U, to which a rope or chain, V, is attached, and the chain is placed across the top of' the stick of wood in the rack and fastened to a hook, W, on the opposite side, when the stick is to be sawed;A and by means of the crank, ratchet, and dog, X, on the outer end of the roller T, the chain is' Wound once or twice around the wiudlass U, to tighten the chain upon the stick of wood,- so as to hold the stickl perfectly steady in the racks S while the 'saws are operating, and the chain V is loosened by reversing the crank vX and unhooking the chain at W.

The sliding framed may be operated inthe centr 'of the machine, by the' crank G and pitman H, or it may be operated by a pitman at the side of themachine, and the fiywheel F placed -in the Ycentre of the shaft E, instead of the crank G.

One saw may also be used, instead of the two',when deemed necessary, by merely adjusting or shifting one of the saws L, and one of its guides R, to the centre of the machine.

I do not claim wood-saws operated by a slide, cogwheels, fly-wheel, and crank-motion, as they have been used before; but

What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement, herein described, of weights N N, iu front ofthe saw-frames, with their guides It R, and the roller T, ratchet and dog X, windlass and pin U, rope V, and hook W, when constructed and operating as and for the purposes set forth.
